Methodology ContinuedMethodology Continued

Spatial analysis • Guarantee snow for at least 5 months a year

(select)• Have mountains from at least 3500 meters

(select)• Be close to existing infrastucture:

o 5 km from an existing road (buffer)o 50 km from an interstate highway (buffer)o 200 km from a major airport (>1,000,000 passenger/year)

(buffer)

ConclusionsConclusions

ArcGis is a very powerful toolLots of free data available on the netPowerful processor and graphics

card needed to work with animationsHigher resolution DEM would give

more accurate resultsDraping with aerial pictures would

give more realistic scene
